[Quantitative study of alpha-1-antitrypsin in an ethnic group of Ivory Coast: the Abrons]

A logarithmic-normal distribution of the concentrations of alpha1AT in 578 Abrons in Ivory Coast was found. A significant, negative logarithmic regression of alpha1AT rates according to age is demonstrated. alpha1AT rate = 0,376 (log age) + 3,003 The quantitative analysis by immunoprecipitation of Technicon only does not permit a definitive conclusion as to the presence of allele Z.
